Drop 'inline' from all the *_mod_init_arch() functions so that the
compiler will warn about any bugs where they are unused due to not being
wired up properly. (There are no such bugs currently, so this just
establishes a more robust convention for the future. Of course, these
functions also tend to get inlined anyway, regardless of the keyword.)

Since sha512_kunit tests the fallback code paths without using
crypto_simd_disabled_for_test, make the SHA-512 code just use the
underlying may_use_simd() and irq_fpu_usable() functions directly
instead of crypto_simd_usable(). This eliminates an unnecessary layer.

Instead of exposing the arm-optimized SHA-512 code via arm-specific
crypto_shash algorithms, instead just implement the sha512_blocks()
library function. This is much simpler, it makes the SHA-512 (and
SHA-384) library functions be arm-optimized, and it fixes the
longstanding issue where the arm-optimized SHA-512 code was disabled by
default. SHA-512 still remains available through crypto_shash, but
individual architectures no longer need to handle it.
To match sha512_blocks(), change the type of the nblocks parameter of
the assembly functions from int to size_t. The assembly functions
actually already treated it as size_t.
